... Abstract Simulation of Water-Alternating-Gas (WAG) Experiments require precise estimation of hysteresis phenomenon in three-phase relative permeability. Most of the research available in the literature are focused on experiments performed on sandstone rocks and the study of carbonate rocks has...

... and documented in literature. On the other hand, very few studies have been conducted on carbonate rocks and less data is available. Therefore, this paper provides a comprehensive review of several important research studies published on CDC over the past few decades for both sandstone and carbonate reservoirs...

... in our country practically began only in the post-war years. In the special petrography laboratory carbonate rocks composing various stratigraphic complexes of almost all oil and gas provinces of the Soviet Union were studied, and in particular, Paleozoic carbonate strata of the Timan-Pechora province...

... surface asperities failure. The improvement in fracture surface hardness can mitigate the abovementioned challenges and sustain the fracture conductivity. This research targeted enhancing carbonate rock's hardness by forming minerals harder than calcite. Carbonate rocks, namely dolomite, limestone...

... for Enhanced Oil Recovery (EOR) are negatively charged. It has long been assumed that the rock surface is primarily positively charged in carbonate rock. The argument of electrostatic attractive forces indicates high loss of polymer due to adsorption. However, the rock surface charge in carbonates may vary...

... values, and improve oil displacement efficiency. There are limited studies on the impact of dynamic wettability alteration on multiphase fluid flow in heterogeneous carbonate rocks. The dynamics of pore-by-pore displacement by smart waterflooding is still unclear. The objective of this research...

... The structure of carbonate formations is variegated and often layered ( Burchette, 2012 ). This means that the interplay between the laser and the beam will be complex. There lies the need to characterize the process in-depth; to understand the effects of laser irradiation on carbonate rocks...

... in pore-scale characterization. Synchrotron-based X-ray imaging is an advanced technique that is capable of capturing the dynamics of pore fluids at the microscopic scale. The aim of this project is to investigate the pore-scale flow of AS flooding at two different salinities in carbonate rocks using real...

... to the interaction of the drilling/fracturing fluid with the layered-matrix e.g. interaction of water-based-mud with reactive clay minerals. This paper focuses on the impacts of the pore fluids redistribution on wellbore stability in organic rich carbonate rocks. The experimental method consisted of measuring...

...) the petrography and diagenesis of TZ are well studied; 3) the carbonate rocks are qualitatively and quantitatively classified into three types: matrix, fractured and vuggy; 4) digital imaging technique, generally, proves to be a powerful tool for characterization of TZs in carbonate reservoirs. Reservoir...

... in stimulated carbonate rock is the loss of near wellbore formation compressive strength which may results in casing collapse under extreme conditions. Field studies have shown that the failure of acidized rock may cause damage and thereby negatively impact production. In this work, an integrated analysis...

... them. This paper describes the interactions between injectant and carbonate rocks during carbonated water injection based on the results of core flood experiments at various conditions. The core experiments were conducted at 30 °C and 500 psig using carbonated rocks mainly composed of calcite. Results...

... was Rhodamine-B, procured from Alfa Aesar. The fluorescence excitation and emission wavelengths of Rhodamine-B are in the range of 514-568 nm and 570-600 nm respectively. For etching the carbonate rock matrix we used 0.25 M hydrochloric (HCl) acid prepared by dilution of 35 % (12 M) HCl (technical grade) from...

... the methodology is not enough mature yet. The difficulty is higher for complex media like those composed carbonate rocks, such media are known to be highly heterogeneous. The subsurface of Abu Dhabi region is known to be mainly composed of carbonate rocks. We developed a new method to estimate the intrinsic...

.... And in the Middle East, around 70% of oil is reserved within the carbonate rocks [ 1 ]. Most of these rocks are oil-wet. According to Treiber et al [ 2 ], 8% of them are water-wet, 8% are intermediate-wet and 84% is oil-wet. For micro/nano pores with oil-wet surface, the Capillary number is small, which means...

... geochemical effects of CO 2 on carbonates and the coupled chemical–mechanical effects. The carbon dioxide dissolves in water forming bicarbonate which will dissociate to carbonic acid. This acid dissolves calcites in carbonate rocks. As a result, the mechanical properties of the aquifer changes through...

... are mixed-wet or oil-wet as a consequence hereof. Thus, insight into which molecules actually bind to the carbonate rock, estimation of molecule-specific relative adsorption affinities and the importance of the crystalline calcite structure is pivotal to decipher the origin of wettability in carbonate...

Abstract We conducted laboratory measurements of V p (compressional waves), V s (shear waves), porosity and permeability on forty nine dry carbonate core plug samples at ambient pressure and temperature. We also, performed an initial lithological description, based on Dunham's carbonate rock...
